NEW YORK (Reuters Health) - In a pilot study of patients with cutaneous T-cell lymphoma (CTCL), treatment with the anti-TNF agent etanercept (Enbrel; Immunex) was safe and generally well tolerated and showed beneficial clinical effects in patients with early, but not advanced disease.
TNF-alpha is believed to play a pathogenic role in CTCL, Dr. Razelle Kurzrock and colleagues from the University of Texas M. D. Anderson Cancer Center in Houston note in the August issue of the Journal of the American Academy of Dermatology.
To investigate the possible effect of inhibiting TNF-alpha, they treated 13 patients with relapsed, heavily pretreated CTCL with etanercept at a dose of 25 milligrams subcutaneously twice weekly for 2 months. Of the 12 evaluable patients, 3 had stage I-IIA disease and 9 had stage IIB-IV disease.
According to the team, etanercept induced partial remission in one patient (8%) and minor response in one patient (8%). Both of these responders had Stage IB disease (without transformation). None of the 10 patients with advanced disease and/or large cell transformation responded.
Based on this pilot study, the researchers conclude that the effect of etanercept in a larger cohort of patients with early disease “merits investigation,” and that dose-escalation should be considered given the observed “excellent tolerance.”
